' MACHINE FOR FORMING AND FLANGING- CAN BODIES.

Application filed August 26, 1920. Serial No. 466,125.

To all whom it may concern.

Be it known that 1, PETER Know, a c1t1- zen of the United States of America, residing in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Machinery for Forming and F langing Can Bodies, of which the following is a specification.

T his invention relates to can making machinery or the like, and aims to provide improvements therein.

The present invention provides a machine wherein the consecutive steps of body-forming and fianging may be satisfactorily performed.

The invention further provides a novel combination and stub-combinations for carrying out the combined functions of body forming and flanging, hereinafter more fully set forth.

The invention further provides a novel means for fianging a can body, this feature of the invention, however, being more broadly claimed in my co-pending applica tion, Serial No. 418,435, filed October 21, 1920, and patented Jan. 10, 1922, No. 1,403,120.

An embodiment of the invention is illustrated in the accompanying drawings.

In said drawings Figure 1 is a view in elevation of the delivery end of a body-making machine, showing a part of the body-forming means, and the flanging means;

Fig. 2 is a longitudinal sectional view, showing essentially the same parts as shown in Fig. 1;

Fig. 3 is a sectional view, on the line TTIIII, Fig. 2;

Fig. 4 is a sectional view of the ejecting mec-hanismiat the delivery end of the mahim, the section being at 90 degrees to the plane of the parts shown in Figs. 1 and 2;

Fig. 5 is an enlarged sectional View, on the line VV. Fig. 2; and

Fig. 6 is a sectional view on the line 66, Fig. 1.

Referring to the drawings, A designates the body-forming part of the machine, and B the fianging part of the mechanism.

Numeral 1O designates a horn, upon which body blanks, in the necessary preliminary form, are placed or fed, and wrapped around the horn. in well known manner, as by means of wings, or the like. Such wing folders are shown at 2, Fig. 6, and are conveniently actuated by rods 3 connected to levers f having a working connection 5, and one of which may be driven by a rod 6 sliding in a part of the frame and connected by a link 7 to an eccentric pin on the face of a disk 8, driven from the shaft 101 by means of bevel gears 9. When the edges of the blank are brought together and overlapped or interlocked, they are pressed together by a bumper 12, or the like, to form a seam. -This seam usually v forms an inner projection upon the inner side of the can body, and the horn. is preferably provided with a groove 14, in which said seam is adapted to slide, and preferably be guided. These features of the invention may be of any well known construction, such,vfor example, as shown in my' United -States Patent No. 1,246,437, dated November The horn 10 is preferably extended, and forms part of the flanging mechanism B. The horn is preferably made up of a plurality of longitudinal sections 15, 16, 17 and 18. The flanging means preferably comprises one or more groups 20 of segments 21, adapted to be moved across the planes of the side or sides of the can body, and turn the edge portion over to form a flange, such as is used for forming, with the inturned edge of a so-called can head or end, a so-called double seam. Preferably, two groups 20 of these segments are provided, in order to flange the two ends of a can body, as illustrated. Each group 20 of segments is preferably interposed between two sections of the horn, and lies substantially flush with the surface of the horn, when in collapsed position. 7

The abutting surfaces of the longitudinal horn sections act to confine the segments 21, as respects movement longitudinally of the horn. i

The horn section between two groups 20 of segments, as, for example, the section 17, may be replaceable,'so that it can be removed and replaced by another for can bodies of different, length or height.

When the can body is in position for flanging, it is preferably exteriorly confined, by means of segments 25, conveniently mounted upon a ring bracket 26, in such manner as to move radially toward and from the horn, and to form a closed ring around the horn,

when moved in against the can body. A ring 28, having cam surfaces 29 thereon, conveniently serves for moving the segments 25 (by contact with the rollers 29 together toward the horn, and springs 30 conveniently move the segments 25 apart, when this is permitted by the cam ring 28; A rod 33 serves for oscillating the cam ring. With two group's 20 of segments, preferably two groups of confining segments 25 are provided, and these are preferably mounted in frames which are relatively movable so as to adjust the distance between the groups of segments 25, when the horn section 17 is replaced with another for alonger or shorter can body.

Means are provided for spreading apart and drawing together the segments 21. These means are conveniently a wedge block 35, which wedge block preferably has a positive connection to the segments, such connection being conveniently effected by providing the wedge block with, or making it in the form of, an undercut or dovetail tenon 36, adapted to engage in corresponding grooves or mortices in the segments, as indicated at 37. The wedge block or blocks are moved back and forth, in order to actuate the segments. A rod 40, which is preferably hollow, is provided for moving the wedge block or wedge blocks, and, where two wedge blocks are employed, a suitable sleeve 41 is provided for operating the two in unison. One end of the rod is conveniently beveled, as indicated at 43, and is moved in one direction by a block 45 having a corresponding beveled part 46, Which block 45 is moved toward the rod 40, by a reciprocatory rod 47. The block 45 is here shown as separate from the rod 47, and as housed in the horn 10, in which case the rod 47 may have a very short stroke. The rod 40, together with its part 41, is moved in a reverse direction by a spring 48, bearing upon one of the wedge blocks through a plate 49. The spring 48, at its opposite end, conveniently bears against the closed end 50 of the hollow horn section 18. Pins 52, fixed upon the plate 49, and projecting through holes 53 in the end 50, serve to guide the plate.

The longitudinal sections of the horn are conveniently tied together by a tie rod 60, which projects through the hollow rod 40 and the piece 41, and further serves as av guide for said hollow rods. The tie rod extends through the closed end 50 of the end section 18, and nuts 62 serve to confine the parts in alinement upon said tie rod. The tie rod may screw into the end section 15 of the horn, which is fastened to a bracket upon the frame, as indicated at 64.

The block 45 is preferably bifurcated at its working end, as indicated at 65, Fig. 5,

and the rod 47 ,which' makes intermittent contact with said block to cause it to actuate said rod 40, is mounted upon a reciprocatoryor circumference of the horn, so as to admit of pressing the inclined face of .the block 45 toward the axis of the horn to drive the said rod 40, on the instroke of the slide 66, and on the outstroke of said slide, when the end of said rod 47 is out of contact with said block 45 to admit of the feed of can bodies along said horn.

Suitable feed mechanism is provided for feeding the can bodies along the horn. This feed mechanism conveniently comprises a reciprocatory feed bar 70, having a plurality of feed fingers 71, said feed fingers being conveniently housed and guided in agroove 72 in the horn.

A suitable ejecting means (Fig. 4) is preferably provided for ejecting the flanged can bodies from the horn. The ejecting mechanism preferably comprises one or more arms 81 having claws 82 at the end, which claws are adapted to engage the flanged end of the can body and drag the can body off of the horn. The fingers 80 are preferably mounted upon a carriage 83 which reciprocates upon a track or way 85 upon a suitable part of the frame. The claws 82 are preferably beveled, as indicated at 87, whereby, on their movement. into position behind the flange, they may ride over the flange. The arms 81 are preferably pivoted, as indicated at 88, and have rear projections 89, with beveled ends, adapted to strike against projections 90, which projections are adapted to turn the arms 81 on their pivots in such manner as to move the claws away from the can body, and allow the can body to drop, after it has been dragged off the horn. Stops 91 may be provided for limiting the inward movement of the arms 81. These stops 91 may be conveniently in the form of bolts 91 passing through the rear projections 89 on said arms 81, and having nuts 91 thereon for limiting the outward movement of said rear extensions 89.

The reciprocatory carriage 83 is preferably provided with a striking part or projection 92, which is adaptedto strike against the ends of the pins 52, and positively move the Wedge blocks 35through the plate 49 and intermediate rod 4], in case of binding of any of the parts, which would prevent the spring 48 from returning the parts of the flanging mechanism to collapsed position.

Motion is imparted to the parts of the fianging and ejecting mechanism, preferably through a shaft 100 (Figs. 1 and 6), which derives its motion from one of the main driving shafts 101 of the machine, through a pair of gears 103. The shaft 100 conveniently has thereon an eccentric and strap 105, adapted to impart a reciprocatory movement to the slide 66 carrying the rod 47 for actuating the wedge blocks 35. A crank pin 107 on said shaft 100 also serves, through a series of connecting rods and links 108, to actuate the cam 28, which acts upon the exterior confining segments 25.

A second crank pin 110, Fig. 6 (on the end of shaft 100, at the opposite side of the machine from pin 107) may serve for reciprocating the carriage 83, acting through a connecting rod 111, lever 112, and link 113.

0peration.The forming mechanism A acts as heretofore described, or according to any well-known way, to form a tubular can body, usually with a seam having an inner projection on the inner side of the can body. The feed fingers 71, on the reciprocatory feed bar 70, advance the tubular can body from the forming position to the fianging position, through one or more idle positions, as may be desired. When the can body passes the rod 47, which actuates the rod 40 through the block 45, the slide 66 is in its lower position, so that the rod 47 is beyond the periphery of the horn, and hence allows the can body to slide past it. The feed fingers 71 feed the can bodies onto the part of the horn which forms part of the flanging mechanism, the seam in the can meanwhile preferably slidingin the groove 14, so as to present the can body in the same position in the flanging mechanism as it had in the forming mechanism, as regards the axis of the horn. In the flanging position, the body is confined by the exterior segments 25, which are moved inward by the cam ring 28, which latter receives its motion through the rods 33 and 108, lever 109, and link 109 connected to the eccentric pin'107. When the segmental confining parts 25 are moved inward, the

- segments 21 of the edge-turning or flangeforming units are spread, so as to turn the edge portions of the can body around the corners of the confining segments, said edgeturning segments 21 being spread by the wedge block 35, which is moved by the hollow rod 40, which latter is moved by the action on the beveled face thereof, of the beveled face on the block 45, which is struck by the reciprocatory rod 47 The motion of one Wedge block 35 is transmitted'to the other through the rod 41, and the second wedge block 35 bears against the plate 49 and tensions the spring 48, which spring 48, when the rod 47 is not pressing the block 45 into contact with the rod 40, returns or moves in the reverse direction the wedge blocks and associatedparts. By reason of the positive connection between the wedge blocks and the se ments 21, the said segments are drawn or collapsed inward, so that their outer faces are flush with the periphery of the horn.

If there is any binding of parts, the striking part 92 on the ejector carriage, hittin g against the ends of the pins 52, will positively move the wedge blocks 35 and associ- I ated parts in the reverse direction, and hence act to positively return the segments 21 to collapsed position.

After the end or ends of the can body have been flanged and the segments collapsed, the cam ring 28 turns, so as to allow the springs 30 to draw the confining segments 25 away so as to clear the flanges formed on the can body.

The ejecting mechanism meanwhile moves forward, and the claws 82 engage behind one of the flanges on the can body. Upon the reverse movement of the carriage 83, the claws drag the can body after them, finally drawing the can body oif of the end of the horn, whereupon it enters a hopper or chute, as may be desired. The projections 90, striking against the beveled ends 89 of the arms 81, moves said arms around their pivots 88, and withdraw the claws from the can body, thereby making sure of the release of the can body, so that it may fall when it has been slid ofi the horn.
